[JSC] Use SlowPathFrameTracer and fix most of wasm GC operations
https://bugs.webkit.org/show_bug.cgi?id=250502
rdar://104156324
Reviewed by Mark Lam.
Use SlowPathFrameTracer to configure topCallFrame in Wasm LLInt SlowPathes.
And remove storeTopCallFrame since it is no longer used: it was originally
introduced to make VM separate from Wasm::Instance etc. while keeping the
functionality of setting a CallFrame* to VM. But now we wiped this abstraction,
so this SlowPathFrameTracer change cleans up things.
We also fix bugs of wasm GC operations where they do not set topCallFrame
correctly.
They need to set it since they do GC allocation, which can cause ShadowChicken
processing,
and it requires topCallFrame. This patch fixes them.
